Customers are saying

Customers are impressed with the PocketJuice 20,000 mAh Portable Charger's impressive battery life, portability, and economical price. Many appreciate its multiple USB ports and large capacity. However, some customers find the device to be somewhat bulky and heavy. A small number also noted that the charger can get warm during use.
